Abstract
Sixty-nine species of primary insect parasites and 12 associated hyperparasites of the armyworm, Pseudaletia unipuncta (Haw.), are listed. All the species occur in the United States or Canada or both; two have been recorded from the host only in Hawaii.Observations on 23 of the primary species in Canada are reported with particular reference to host-parasite relationships, general distribution, and the degree of parasitism by the principal species. Seven secondary parasites and their primary parasite hosts are discussed.
